ECU software update (2021070027)
I am in the service shop with loss of power/acceleration. They have performed an exhaust regen. The DPF was 82%. They will change the back pressure sensor (due to low boost indication) and remove/check the EGR valve. They are not sure if the ECU software update (2021070027) has anything to do with the problem. It is very new and they have very little history with it. Has anyone heard of any problems with this update?
